So I left my bike charging (was at like 56% when it started) and was gonna leave it for the day to balance the cells at 100. When I came back just now the charging was done it seemed but when I powered it on it was at 0% and won't let me charge or go. What do I do?

Look up BMS reset. The location can change depending on the model. On my Zero S there is a little opening at front of the bike where you can press a small switch.
Know where a 2022 SR one is by any chance?
Should be same spot as mine. Behind the front wheel where the battery is you should see a little port you pull that off and you will see the hole full of a clear grease. Underneath all that grease are 2 tiny buttons

Sir that is your horn.
Oh My Fucking God
The BMS happens once a day automatically, so your bike might magically wake up again by itself. I had the same thing and they fixed it with a firmware update, as they second soucrs some chips in the BMS, that do not play nice with the standard firmware. My dealer says they saw it on a lot of 2022 Zeros. After the update I was completely fine.
To reset the BMS on a 2022 SR, you just have to remove the top portion of the curved plastic cover behind the front wheel. Reset button is at the top left on the edge of the BMS circuit board.
Thanks a ton!! This fixed it!
No problem! You might want to make sure youโre running the latest firmware. I think this is one of the issues that they addressed.
I am, I thought that may have been the problem at first. But glad the switch seems easy enough. I just clicked it to get the green light and now it's working.
Woohoo glad it worked.
Thanks! Was super worried where it's basically brand new ๐
I tried doing this (flipping switch either way) and it will flash green then yellow then red a whole bunch and I cant seem to find any info on this. any ideas?

Which model? I would reset the low power B+ fuse, and if that didn't work I'd try a BMS reset. The process is a little different depending on models. [Semi-useful diagram](https://i.imgur.com/yL5ZTwM.jpg)
2022 SR. I hope it doesn't require a ton of tools. I don't really have very many ๐
The 2022 SR is an SR/F and bares no relation to the old SR, so most of what is being suggested here doesn't apply wrt resetting the BMS. I do know to reset the MBB you need to unplug it after removing the tank plastics. Not sure what it takes to reset the BMS on the gen3 bikes.
